Question 4 (1 point) A balloon is placed in a closed vacuum chamber at STP. The chamber pressure is reduced by half. What happens to the balloon? ) It stays the same volume. ) It expands to four times the volume. It reduces in size by half. It doubles in volume. D View hint for Question 4

To answer this question, we need to apply **Boyle's Law**, which states that for a given amount of gas at constant temperature, the pressure and volume are inversely proportional. Mathematically: Where:- is the initial pressure,- is the initial volume,- is the final pressure,- is the final volume.### Given:- The balloon starts at standard temperature and pressure (STP).- The chamber pressure is reduced by half ( ).- Temperature remains constant.### Step-by-step solution:1. Rearrange Boyle's Law to solve for : 2. Substitute into the equation: 3. This shows that the volume of the balloon doubles when the pressure is halved.### Final Answer:**The balloon doubles in volume.**Correct option: **"It doubles in volume."**
